Hi Folks,
I am trying to make 2 DC motors run exactly same speed with AX3500 control board. I have been trying to do this, I have not found any success on this, So, I would appreciate, any suggestions.
Thank you.

Are you using encoders on each motor?
What kind of speed difference are you measuring? expecting?

Try changing the PID gains so that each motor reaches the desired speed quicker and better tracks the errors reported by the encoder |
